ABSTRACTAttention allows us to rapidly respond to unexpected events, a fundamental capacity for survival. We recorded brain activity from 28 individuals with a total of 1,403 intracortical contacts, while they produced faster manual responses to visual targets preceded by non-predictive attentional cues, which engage exogenous spatial attention. Using a novel spatiotemporal clustering approach, we identified three distinct brain networks: an early visual cluster; an intermediate, predominantly right-hemisphere caudal temporoparietal-prefrontal cluster, sensitive to attentional effects; and a late, predominantly left-hemisphere rostral temporoparietal-prefrontal cluster, sensitive to response-requiring targets. Activity in temporoparietal-prefrontal clusters suggested neural integration of temporally close cues and targets, and was closely related to behavioral responses. These results reveal how cortical networks govern the psychological construct of exogenous attention.One-sentence summaryThe neural basis of human exogenous attention lies in the nexus between perception and action
